Grease ok oil dispensing apparatus



UNITED STATES To HU whom. if )may con-cern.'

lie it known that l` HAxs M. Bon, a citizen ol' the United States, resident ot Minneapolis, county otn llennepin, State o'f Minnesota. have invented certain new and uselul Improvements in Grease or Oil Dispensin, r Apparatus, of which the following is a specltication. I

lhe object of my invention is to provlde an attachment for a grease or oil tank or container by means ot' which lubricant can be drawn out o'l1 the tank and discharged through a suitable nozzle into a hearing, dilierential or any other device where the lubriratingV material is needed.

A further object is 4to provide an apparatus which will besimple and .inexpensive in construction and easily operated.

Other objects of the invention will appeal' from the iollo\vin; r detailed description.

The invention consists generally in various constructions and combinations. all as hereinafterdescribed and particularly pointed out in the claims.

In the accompanying drawings forming part oi this specification,

Figure l is a sideI view. partially in section, ot a dispensinpr apparatus with my invention applied thereto,

Figure 2 Yis a vertical sectional view through the tank attachlnent,

Figures 2i and l are detail views, showingthe metallic disk for holding,- the piston cups in place.

In the drawing, 2 represents a tank or container having' a leg' i5 and caster supports 4 on which the tank is moved conveniently from place to place. 5 is a cover, suitably secured to the top ol' the tank and provided on one side with a project-ingr bracket (i having a vertical socket T therein. At the hottom ol the tank is an outlet. or discharge port S leading to a passa-ge il which terminates in an elbow into which a nipple l1 is tapped. l2 represents a pump head, connected with the other end. of the nipple and containing` a chamber 13, the nipple having a seat` 1-1L t'or al ball valve 15 which normally.

GREASE OR OIL DISPENSING APPARATUS.

Ressued Aug. 1, 1922.

Original No. 1,369,517, dated February 22, 1921, Serial No. 282,139, filed March 12, 1919. Applicatinn for reissue filed May 27. 1922. Serial No. 564,251.

the upst-roke ot the plunger. Av pin 17? iS also provided in the wall of the head `l2-t0 limit the movement of the bal'llvalve l5a toward the discharge port of the head. A piston rod 18 is mounted in said barrel andv has a. head 19 at its lower end that. is tapped to receive a bolt 2() and piston cups 21 are placed back to back on said .boltiid seated Aagainst said head, beingr clamped securely thereon by the tightening of said bolt. These cups' are preferably of leather or some other suitable flexible material and their edges are held in contact with the inner walls of the barrel by suitable means, preferably the metallic. disks 22, preferably of brass, having radial slits 23 in their edges to 'form a series of spring-like tongues 24 which, when the edge of the disk is folded, lap one another slightly on one side, as indicated in Figure 3. and have the function of holding the lexibleedges of the cups against the walls ot the. barrel with a` yield pressure. The disks are made and pressed outwardlyV on the cups when the clamping bolt is tightened and the disks and cups drawn together.' Y

ln making' these brass disks, l eut a` series of radial slits in the edges thereof and then, when the disk is folded to the form shown in Figure Il. the abutting edges of the disks will slide by each other, said edges being slightly offset in the act ot cutting the slits, so that it is only necessary to fold'the` disk to the torni shown in Figure t, when the tongues 24 will assume the 'position illustrated in Figure- 3. These disks I regard as an,importantvfeature of the invention.

Above th lirrel'l lis a housing 25 in which a shat't 26 having an operating handle 27 is journaled and a pinion 2S is mounted on said shaft. to engage the teeth 29 of the piston rod 18. A hollow guide 30 is provided above the housing 25, forming, a 4continuation of the barrel'l and consist-s preferably of a section of pipe inserted into the socket 17, and held rigidly thereby in line with -the barrel to receive the rod 18 when the piston" is raised by the movement of the operatifigi crank 27. The plunger rod and its rack are wholly enclosed by the barrel and the hollow guide 30 and are thereby made. dirt and dust-proof, and the upper end oil the pipe 30, radially mounted in the cover 5, serves as a convenient handle for moving the tank from place to place. By mounting the piston rod in this way I not only thoroughly protect it but avoid the necessity of Iirojeeting the rod a considerable distancer 34 to arrest movement ot the ball when it is raised from its seat by the pressure ot the lubricating. material and allow such material to flow around the ball into the hose secs tion 35 and from thence to the nozzle and he discharged. This head andjits connections are of ordinary pump construction to which I .make vno claim.

In operation, the crank 27 is revolved to raise the plunger. The valve 15 is thereby lifted from its seat and a quantity of the lubricating material is drawn from the tank up into the barrel 15. the valve 34 being closed at this time. As soon as the. suction ot' the plunger ceases, the valve 15a will retffrn to its seat and be forced therebn when t e piston begins its downward movement and the lubricating material accumulated in the barrel will flow down through the chamber 13 and up through the port 31- into the chamber 32 and from thence to the nozzle. the rapidity of the discharge depending. of course, .upon the speed ot descent otl the plunger.

During the movement of the plunger the spring discs22 through their vielding contact with the iexible cups 21. will `form a close joint between said cups and the walls of the barrel and insure the piston. performing its proper function in the operation ot the pump. The amount of lubricant discharged may nbe approxiniatelv determined by the stroke of the pump. I do not, however, rely upon this means for detetmining the quantity ot lubricant discharged;y as provision 'is made in the tank 2 through thc medium ot' a piston in the vtank and an indicator on the cover fi (not shown) through the movement of which the discharge ot' lubricant from the tank accurately measured.
